PHOTOS: Shenzhen's 2nd White Collar Fight Night

From there, white-collar workers faced off in the ring as the crowd cheered, ate and drank before wrapping up Shenzhen's second White Collar Fight Night, which is set to benefit local volunteer group A Heart for China in the form of an estimated RMB100,000 raised in a mid-event charity auction.

Shenzhen-based photographer Mark Fail took the incredible below pictures, showing the highs of the event and even capturing some of the personal lows of the boxers who stepped into the ring and gave it everything they had.
